On orders from President Barack Obama, the U.S. military launched cruise missiles early Thursday against two suspected al-Qaeda sites in Yemen, administration officials told ABC News in a report broadcast on ABC World News with Charles Gibson.

[efoods]One of the targeted sites was a suspected al Qaeda training camp north of the capitol, Sanaa, and the second target was a location where officials said “an imminent attack against a U.S. asset was being planned.”

The Yemen attacks by the U.S. military represent a major escalation of the Obama administration’s campaign against al Qaeda.

In his speech about added troops for Afghanistan earlier this month, President Obama made a brief reference to Yemen, saying, “Where al Qaeda and its allies attempt to establish a foothold — whether in Somalia or Yemen or elsewhere — they must be confronted by growing pressure and strong partnerships.”
